I really liked the idea to have 3 colorations of the website, one for each of my business areas. So as the user clicks through the different pages, the logos etc will change color (orange, blue, green, see attachments). But one color would be fine, too.

The green logo in the "color variations.ai" and "3d logo color variations.ai" is an old revision, the logo on the "green2" files have the new, better, color. I will update this as soon as I get the last update from the designer. 1-2 days.

some copypasta from the old contest:
Sooner or later, the "UG (haftungsbeschränkt)" will change into "GmbH", please take that into account.

Keep in mind, that the full title has only to be present in the imprint of the website, and in the legal documents, but not in the logo ("nachtmann.it" is enough).
